Push-button start works by using a key fob with a radio transponder to communicate with the car’s internal computer. When the button is pressed, it sends a signal to the car's system to check for the key fob's presence. Once detected, the system activates the ignition electronically without needing a physical key turn. This provides convenience and enhanced security as the car can only be started if the key fob is within proximity.
